The Australian motorsports legend John Bowe was given an opportunity to test and review the VAREX Smart Box Bluetooth exhaust controller. He came away highly impressed with the features and functionality. “This (the VAREX Smart Box), is probably the most sophisticated and revolutionary exhaust product I’ve ever seen in my life,” John commented. He reckons that anyone who wants to take full control of their performance exhaust should get the VAREX Smart Box and mufflers. For more information about Varex Smart Box, please click here.
